North America HVAC review: Bait and switch, and horrible, horrible customer service

Bait and switch AND horrible response to my seeking of resolution; paid (a lot) for "UPS Next Day Air" shipping, and it was over a day late... ordered on Friday at 10:18 AM (their site even says that orders by 3 are Next Day), UPS website says they deliver Next Day Air orders on Saturday, AC Part shows up on Monday; whole Friday and weekend of 87 degree temps. Informed them, just wanted credit for the shipping charge; (by the way, they don't answer phones; only method is text). Instead, they dug in their heels, hid behind statements like "... our policy says..." and ". It's not our fault..." taking NO responsibility for ANY of it... horrible, horrible customer experience... race to the bottom and treat your customers like garbage; no empathy, no care. Do not buy anything from these people; they need fix this, but they do not care. So, I'm disputing the whole transaction as a "fraud of service" becauseTHAT is what it is. This could have been easily remedied, but they couldn't see the wisdom of doing that. Don't buy anything from these folks.
